80% — the median of 6 frontier models, resolving by 2029-10-04.

Answer

Gemini (Google): 88% — Bitcoin has doubled within a 12-month window in every single four-year cycle to date, driven by halving shocks and macro liquidity. Historically, 12-month rolling 100%+ gains occur during every multi-year epoch, even as overall volatility structurally decays. The 2028 halving epoch offers another structural supply shock window alongside expected global central bank easing cycles. Only unprecedented institutionalization dampening volatility below equity-index levels or severe global bans would prevent this.

Answer

Claude (Anthropic): 82% — Hinges on at least one strong BTC bull leg (post-2024 halving cycle, next halving ~2028) hitting 100%+ in a year. Bitcoin has doubled within a 12-month window in most years since inception, including 2023, 2020-21, 2019, 2016-17, making this a strong base rate. Four-year halving cycles historically produce violent run-ups, and the window to 2029 covers both the tail of the current cycle and the next halving buildup. Main risk is a structurally calmer market as BTC matures/institutionalizes, which could dampen volatility enough to prevent a clean 100% rolling-year move.

Answer

GPT (OpenAI): 78% — The key hinge is whether the post-2028-halving cycle still produces a normal high-beta Bitcoin advance before 2029. Bitcoin has exceeded a 100% gain over a rolling year in several prior cycle expansions, including 2013, 2017, 2020–21 and 2023–24. The April 2028 halving gives roughly eight months before January 2029; a doubling can also occur from a 2026–28 drawdown base. This falls if institutional ownership and mature derivatives suppress volatility; a sharp post-halving inflow surge would raise it materially.

Answer

Grok (xAI): 71% — 2028-halving cycle must deliver a >2x 12-month close by Dec 2028. Every prior halving (2012/16/20/24) produced at least one 365-day doubling; 2028 is the same supply-cut event. Window ends 1 Jan 2029, only ~8 months after expected Apr 2028 halving, so the rally must begin pre-halving. A deep 2026-27 bear or delayed ETF/regulatory flow would push the move past the cutoff.

Answer

DeepSeek (DeepSeek): 82% — Bitcoin has never gone 12 straight months without a >100% rolling gain in any prior cycle, and 2028's halving sits inside the window. Every post-halving cycle since 2012 produced a >100% rolling 12-month gain within ~18 months of the halving; the next halving lands April 2028, inside the window. The 2024-25 cycle already delivered a >100% rolling gain (Oct 2023-Oct 2024), so the base rate for 'any rolling 12-month doubling before 2029' is near-certain absent a… The main risk is a prolonged bear market through 2027-28 that suppresses the post-halving rally; a spot-ETF-driven regime change or macro shock that kills the four-year…

Answer

Qwen (Alibaba): 62% — Bitcoin has doubled in rolling 12-month windows in every cycle since 2012; the 2024 halving cycle is the live window. BTC has achieved >100% rolling 12-month gains in 2013, 2017, 2021, and 2024 cycles—base rate is ~4/4 cycles, though diminishing returns trend downward. The April 2024 halving means the historically strongest 12-18 month post-halving window runs through mid-2025 to late 2025; if BTC hasn't already doubled from a trough… A sustained macro recession or regulatory crackdown (e.g., US enforcement action on major exchanges) would be the main scenario breaking the pattern; conversely, spot…
